Mountain bike tech continues to work its way across the riser/drop bar divide with the recent announcement of SRAM’s CX1 group and, hot on its heels, RaceFace’s narrow/wide chainrings for 130mm and 110mm road and cyclocross cranks. Allowing for 1x drivetrains without a chain device (though a clutch-type rear mech doesn’t hurt- X0 and X9 Type 2 derailleurs work great with SRAM road shifters), the Cross Narrow/Wide ‘ring is available now in even sizes between 38t and 44t for £50. Not into logos? Flip the chainring around for a stealthier look.
